How do I find the missing lengths?

Answer:

By knowing the formulas for the volume of the solids.

Step-by-step explanation:

To find it out, you need to know the formula for the solids shown such as the cone and the cylinder. The formula for the cone is 1/3hπr². The formula for the cylinder is hπr².

If you were asking for the answers,

Cone:

$\frac{1}{3}*3.14*13*r^2=1959.36\\3.14*13*r^2=5878.08\\13*r^2=1872\\r^2=144\\r=12$

The radius for the cone is 12 inches.

Cylinder:

$h*3.14*20^2=4772.8\\h*20^2=1520\\h*400=1520\\h=3.8$

The height for the cylinder is 3.8 inches.
